不同轮作模式对高寒黑土区土壤养分及马铃薯产量的影响
Effects of Different Crop Rotation Patterns on Soil Nutrients and Potato Yield in Alpine Black Soil Areas
摘要
Abstract
[Objective]To study the effects of different crop rotation patterns on soil nutrients and potato yield in the alpine black soil area.[Method]6 treatments were set as potato-wheat-beet-potato(St-Ta-Bv-St),potato-water thistle-wheat-potato(St-Sm-Ta-St);wheat-beet-wheat-potato(Ta-Bv-Ta-St),oilseed rape-wheat-beet-potato(Bn-Ta-Bv-St),wheat-oilseed rape-barley-potato(Ta-Bn-Hv-St);oilseed rape-wheat-potato-potato(CK).[Result]Compared with CK,different crop rotation patterns promoted the content of organic matter,total nitro-gen,total phosphorus,total potassium,alkaline dissolved nitrogen,quick-acting phosphorus and quick-acting phosphorus in the 0-20 cm soil layer.The Ta-Bv-Ta-St treatment had a significant promotion of soil nutrients,and the content of soil organic matter,total potassium and quick-acting nutrients was significantly increased compared with CK by 82.22%,123.89%,140.08%and 20.06%;Bn-Ta-Bv-St treatment was the second highest,soil total nitrogen and alkaline dissolved nitrogen content significantly increased by 72.78%and 37.95%compared with CK.Different crop rotation patterns significantly improved potato yields compared with CK,and Ta-Bv-Ta-St treatment had the highest yield of 58.02 t/hm2.There were highly significant differences in the commercial potato yields of different crop rotation patterns,with Ta-Bn-Hv-St treatment having the highest commercial potato yield of 88.76%.Potato yield was significantly and positively correlated with soil organic matter and total potassium(P＜0.05),and highly significant and positively correlated with quick-acting potassium(P＜0.01).[Conclusion]Ta-Bv-Ta-St,St-Sm-Ta-St and Ta-Bn-Hv-St crop rotation patterns are more capable of improving the soil environment and potato yield than other treatments,and are suitable for popularisation in the alpine black soil area,among which Ta-Bv-Ta-St was more effective in improving the high-yield and high-efficiency cultivation technology of potato.关键词
